Funny how in Melee 1 remix was the norm, maybe 2 if the franchise was lucky enough. Now we get 7 for Banjo and some feel its not a lot. it goes to show how Brawl onward we are spoiled, and how great Banjo's soundtrack is that 10 tracks doesn't cover all the best ones.
Also in Melee if I recall nobody had "alternate costumes" just recolors. Wario I think was the first to have this, and since Brawl again we've been spoiled. I know Banjo has many opportunities for outfits but I am happy with the recolors
It's fine to nitpick little things they didn't get compared to other members of the cast, but honestly we got more here than we ever would have pre Smash 4 era. Castlevania got 34 songs and 13 remixes sure, but no alt costumes besides an Echo. Same for Street Fighter which has 38 songs and only 4 remixes. Dragon Quest got 4 costumes but 0 new songs. Every Smash character has checks and balances, I don't think any one of them got more than the others. Banjo got more than some, and less than some others, it feels pretty generous to me
